Specification of Letters Patent.

Patented May 20, 1919.

Application filed October 4, 1916. Serial No. 123,687.

To all whom it may concern Be it known that I, WILLIAM G. Grrenins,

One of the objects of the present inven-.

tion is to produce a simple and very eflicient means for squeezing the .material to be washed.' Another object is to provide a simple means for squeezing the material at re lar intervals while it. is carried by a rotating carrier. A further object is to provide means for adjusting or regulating the squeezer while the carrier is in motion.

With the foregoing and other objects in View the invention comprises the novel con.-

struction, combinationand arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention; however, it is to be understood that the invention comprehends changes, variations and modifications which come within the scope of the claims hereunto appended.

Figure I is a side elevation of a washing machine constructed in accordance with the invention, a portion of the liquid receptacle being broken away to show the guide cams which direct the squeezer toward and away from a portion of the rotary carrier.

Fig. II is a vertical section of the machine looking from the opposite side to that shown in Fig. I, a portion of the carrier being broken away to show the guide cams.

Fig. III is a"vertical axial section taken approximately through the center of the power shaft.

Fig. IVfsa vertical section, on a reduced scale, taken on line IVIV, Fig. III.

7 {A designates a cylindrical liquid recep-- tacle comprising a cylindrical wall 1 and side walls QanH -S, A door 4 (Fig. II) norlly c1oseanopeniug in the cylindrical wall 1. The liquid receptacle is stationary and it is supported by legs 5.

A rotary carrier B, arranged within the liquid receptacle A, is adapted to receive the material to be washed. This carrier comprises a perforated cylindrical wall 6 and side walls 7 and 8.secured to said cylin drical wall. A. perforated axial partition 9 forms part of the'rotary carrier and divides it into two semi-circular compartments. 1O

designates doors (Fig. II) carried by the carrier B and adaptedto register with the door 4 to allow the material to be introduced into and removed from the two compartments of the carrier. A central power shaft, arranged at the axis of the rotary carrier, comprises trunnions 11 (Fig. III) extending from-the side walls of the car? rier and journaled in the side walls of the stationary liquid receptacle. Any suitable power mechanism may be associated with the power shaft to rotate the carrier continuously. Q i

The means for squeezing the material to :be washed comprises a pair of perforated arcuate wings'12, oneto each compartment, pivoted. to the rotary carrier at 13 and adapted to move toward andawayfrom the partition 9 for the purpose of squeezing the, material. Each squeezer wing 12 is provided with a pin 14 which extends through an arcuate slot .15 in the carrier wall 7. These slots are formed concentrically to the respective pivots 13' so as to allow the carrier wings to oscillate about the axes of said pivots. v

Arcuate guide cams 16 and 17 secured to the wall '2 of the stationary liquid receptacle, are arranged adjacent to each other to form an arcuate slot for the reception of the pins 14 which. project fromthe squeezer wings. The carrier turns in the direction indicated by arrows in Figs. I, II and IV, andduring each revolution thereof,'-the pins .14 strike the cam guide 16 and enter the space between the guides 16 and 17. The squeezer wings "are thus shifted toward and away from the partition 9 in response to the rotary movement of the carrier. It will be observed that the cam guides 16 and 17 are so arranged as to allow the pins 14 to travel entirely through the arcuate space between said guides. The pins 14 enter this space at the righthand side of Fig. 11 and pass therefrom at theleft sid'e. Obviously, this tary carrier, but they may also be adjustedv action will cause the squeezer wings12 to oscillate about the axes of their pivots 13.

The machine is adapted to wash filtering material such as filter clothsor pulp, and it may also be utilized in washing animal skins and more delicate material such as laces, silks, etc. The material to be washed is confined in the rotary carrier B and the cleansing liquid is confined in the lower portion of the receptacle A. After being saturated with the liquid, the material is carried upwardly on the partition 9 which travels in the direction indicated bythe arrow in Fig. 11. Thereafter, the material is squeezed between a squeezer wing 12 and the partition 9, the water being forced through the perforations in said parts. .When a squeezer wing moves away from the partition to release the material, the partition forms an inclined slideway for the material and the latter, moving downwardly by gravity, strikes the obstructions or rubbers 19. The material then unfolds or spreads out and passes into the water at the lower portion of the receptacle B. It will be noted that the material is squeezed while it lies in a plane above the water and then permitted to unfold and absorb the water before the next squeezing operation.

en a squeezer wing 12 occupies the position shown. at the left side of Fig. 11, it

lies concentric with the cylindrical wall 6 of the carrieran'd at this time a bar 20, se- 7 scribed. By adjusting these cams towardand away from the axis of the rotary carrier, the movements of the squeezer wings may be varied or regulated. When the cams occupy their various operative positions they lie eccentrically to the axis of the roto an abnormal position (Fig. IV) wherein their arcuate faces are approximately concentric with the axis of the carrier. When the guide cams 16 and 17 occupy the last mentioned positions, the pins 14 projecting from the squeezers, will travel in a circular path and the squeezers will not be deflected toward the partition 9. This is an advantage in treating material that should not be subjected to the squeezing operations. When the cams are adjusted to eliminate the squeezing action, a short arcuate retaining bar 24 forms a continuation of the cam 17 and forms partof the means for retaining the sque'ezers in their inoperative ositions. When the pins 14, projecting irom the squeezers, pass from the cam 17, they tend to swing toward the axis of the carrier, but a movement of this kind is then prevented by the stationary retaining bar 24.

The adjustable operating means, whereby the cam guides may be adjusted and held in 1 different positions, comprises arms 25. and 26 (Fig. I) rigidly secured to the cam guides by means of the pivot bolts 21 and 22, respectively, a yieldable device connecting these arms as will be presentlydescribed, a link 27 pivoted at 28 to the arm 26, an operating arm 29 pivoted to link 27, a worm gear 30- secured to arm 29, a rotatable Worm 31 meshing with said worm gear, and an operating wheel 32 secured to the worm 31. Both of the cams 16 and 1? may be adjusted simultaneously by. turning the operating wheel 32, and it is important to note that this may be accomplished while the rotary carrier is in motion.

The yieldable connection between the arms 25 and 26 (Fig. 1) comprises a T shaped spring seat 33 pivoted to the arm 26, rods 34 rigidly connecting said spring seat 33 to a spring seat 35, an intermediate spring seat 36 slidably fitted to the rods 34, a connecting rod 37 securing the intermediate spring seat 36 to the arm 25, springs 38 between the spring seats 35 and 36, and springs 39 between the spring seats 33 and 36. This yieldable connecting device allows the upper cam guide 16 to move upwardly on its pivot '21, thereby preventing the parts from being irijured by severe squeezing operations. When the cam guide 15 moves upwardly from the osition shown in Fig. I, the arm 25, rod 3 and spring seat 36 also move upwardly so as to compress the springs 38; and when the parts are restored by the springs 38 the spring seat 36 is forced down wardly on springs 39. The long springs 38 allow the cam guide 16 to move upwardly and they serve as means for restoring said cam guide. The springs 39 serve as shock absorbers and allow-the spring seat 36 to be forced downwardly without jarring or hammering the yieldable connecting device.
